Old Kent Road at the Kentish Drovers left. The picture was taken between 1911 and 1913. The tram’s fleet number is seen in the photograph as ‘191’. The very first tram in London carried the number ‘1’ and all subsequent trams were numbered sequentially so this is the 191st London County Council electric tram. The numbering continued over the years and the last numbered London Transport tram was 2529 – after which trams ceased to run in London, in 1952. In general, odd numbers were used for routes north of the Thames and even numbers were used for routes south of the river. Anomalies arose with trams on routes that crossed one of the bridges over the Thames because these trams ran both north and south of the river.
